Abstract :
Effects of damping coefficient and spring stiffness on the transfer characteristics of the seat suspension system is studied. Based on the designed magneto-rheological(MR) seat suspension, the vibration characteristic experiment system is set up. Considering the change of damping and stiffness of MR damper caused by current, the vibration characteristics experiment about the seat suspension system is made. The results show that increasing the input current can reduce the transmissibility of the seat suspension system before the 1st order resonance frequency, and it presents a strong controllability. Meanwhile, it verifies the correctness of the theoretical simulation from the point of the experiment.
